Marta Kostyuk, the No. 11 seed with a 27-6 record in 2026 including titles in Madrid and Rouen, faces Sofia Kenin in the Cincinnati Open round of 64. Kostyuk arrives with strong hard-court momentum after straight-sets wins over Katherine Sebov and Madison Keys in Toronto, despite a loss to Iga Swiatek. Kenin, ranked outside the top 100 with a 5-18 seasonal mark, secured her first hard-court victory since January by rallying past Eva Lys in the opener. The matchup favors Kostyuk’s consistent baseline game and recent results over Kenin’s lower ranking and limited success, though the American’s experience and head-to-head edge introduce some uncertainty on the fast outdoor courts.
